STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

fmtmethionyl-tRNA formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family. (311 aa)    
Predicted Functional Partners:
DIP1321
Conserved hypothetical protein; Similar to Mycobacterium tuberculosis hypothetical 48.5 kDa protein Rv1407 or MT1451 or MTCY21B4.24 SWALL:YE07_MYCTU (SWALL:P71675) (457 aa) fasta scores: E(): 6.2e-86, 55.4% id in 453 aa, and to Escherichia coli Sun protein Sun or Fmu or Fmv or RsmB or B3289 SWALL:SUN_ECOLI (SWALL:P36929) (429 aa) fasta scores: E(): 1.2e-31, 33.63% id in 449 aa; Belongs to the class I-like SAM-binding methyltransferase superfamily. RsmB/NOP family.
 
  
 0.975
glyA
Serine hydroxymethyltransferase; Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism.
     
 0.969
def-2
Putative peptide deformylase; Removes the formyl group from the N-terminal Met of newly synthesized proteins. Requires at least a dipeptide for an efficient rate of reaction. N-terminal L-methionine is a prerequisite for activity but the enzyme has broad specificity at other positions.
 
 0.963
folD
Methylenetetrahydrofolate dehydrogenase; Catalyzes the oxidation of 5,10-methylenetetrahydrofolate to 5,10-methenyltetrahydrofolate and then the hydrolysis of 5,10- methenyltetrahydrofolate to 10-formyltetrahydrofolate.
 
 
 0.961
purN
5'-phosphoribosylglycinamide formyltransferase; Catalyzes the transfer of a formyl group from 10- formyltetrahydrofolate to 5-phospho-ribosyl-glycinamide (GAR), producing 5-phospho-ribosyl-N-formylglycinamide (FGAR) and tetrahydrofolate.
    
 0.955
thyX
Conserved hypothetical protein; Catalyzes the reductive methylation of 2'-deoxyuridine-5'- monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor, and NADPH and FADH(2) as the reductant.
     
 0.947
DIP0824
Putative folate reductase; Similar to Mycobacterium avium dihydrofolate reductase FolA TR:O30463 (EMBL:AF006616) (181 aa) fasta scores: E(): 2e-22, 46.1% id in 167 aa, and to Escherichia coli dihydrofolate reductase FolA or TmrA or B0048 SW:DYR_ECOLI (P00379) (159 aa) fasta scores: E(): 1.5e-13, 42.76% id in 152 aa.
  
 
 0.931
metH
5-methyltetrahydrofolate--homocysteine methyltransferase; Catalyzes the transfer of a methyl group from methyl- cobalamin to homocysteine, yielding enzyme-bound cob(I)alamin and methionine. Subsequently, remethylates the cofactor using methyltetrahydrofolate.
    
 0.919
metG
methionyl-tRNA synthetase; Is required not only for elongation of protein synthesis but also for the initiation of all mRNA translation through initiator tRNA(fMet) aminoacylation.
     
 0.915
DIP2057
Putative phosphoribosylglycinamide formyltransferase; Similar to although shorter in its N-terminal region than Pasteurella haemolytica probable phosphoribosylglycinamide formyltransferase 2 PurT or Mpa1 SWALL:PURT_PASHA (SWALL:P46927) (392 aa) fasta scores: E(): 1e-12, 32.24% id in 276 aa, than Bacillus subtilis phosphoribosylglycinamide formyltransferase 2 PurT SWALL:PURT_BACSU (SWALL:P39771) (384 aa) fasta scores: E(): 3.8e-12, 35.81% id in 282 aa, and than Escherichia coli phosphoribosylglycinamide formyltransferase 2 PurT or B1849 SWALL:PURT_ECOLI (SWALL:P33221) (391 aa) fasta sco [...]
